the ball will stay moving at the same rate of speed until something happens and stop it
"increments of 8" means the major divisions are 0,8,16,24 ?
<span>x axis, calculate the moment arms from 0 </span>
<span>3x4, 2x12, 1x20 </span>
<span>from an arbitrary C </span>
<span>3(c-4) + 2(c-12) + (c-20) = 0 </span>
<span>3c - 12 + 2c -24 + c - 20 = 0 </span>
<span>6c = 56 </span>
<span>c = 9.33 </span>
<span>y axis </span>
<span>3x3, 1x12, 2x20 </span>
<span>3(c-4) + 1(c-12) +2 (c-20) = 0 </span>
<span>3c - 12 + c - 12 + 2c - 40 = 0 </span>
<span>6c = 64 </span>
<span>c = 10.67 </span>
<span>so center is x = 9.33, y = 10.67 </span>
Answer:
the units of work and energy is joule and unit of power is Watt
For the motion of the plane it is given to us that it travel 15.0 km in 15.3 s
So here we can use the formula of average velocity to find it
formula is given as ratio of total displacement and total time
here it is given that
time = 15.3 s
we need to convert the time into hour as the speed is required in km/h
so we know that
now by the above formula
so the velocity of the plane would be 3529.4 km/h
